Rename asset file names on upload

Question

Hi All,

Is there a way to overlay/interject the CreateAssetServlet and make sure the filename contains valid (allowed characters)? Or even the js calling the servlet to pass a desired filename?

I see here that there are valid characters that are allowed in classic ui. However when I upload using a space or other characters, the filename still has those (AEM 6.5.10 On premise)

I see http://experience-aem.blogspot.com/2020/08/aem-6550-modify-filename-on-upload-before-executing-dam-update-asset-workflow.html where a Filter is used but still looking to see if a simple interjection can be used instead of using a filter that seems to be doing much.

Another option I have is use a custom workflow (not impacting dam update wf) and add a process step to rename the file name that is suitable.

Hi @shubham_borole ,

If you want to rename the file name before uploading to DAM. FileUpload.js is the best way to go,

To achieve this, we would need to overlay the fileupload.js in : /libs/dam/gui/coral/components/commons/fileupload/clientlibs/fileupload/js/fileupload.js

In that file you will notice, there are multiple operations happening on the asset name before uploading.

Just create a function to replace certain chars and then call it within any such operations.

@shubham_borole ,

Filter is good way to proceed in your use case because if you want to rename the file before you save it is an efficient way to rename the asset file than renaming asset later.

if you do not have any other process such as assigning metadata or any other activities then you can consider implementing sling resource change listener.
